The purpose of this feasibility study is to evaluate the benefit of unilateral implantation in adults who have severe to profound sensorineural hearing loss in one ear, and up to moderate sensorineural hearing loss in the other ear (asymmetric hearing loss).

Hereditary hearing impairment is a genetically heterogeneous disorder that can be caused by mutations in any one of hundreds of different genes. Approximately 20 genes have now been identified in which mutations can cause nonsyndromic sensorineural hearing loss. The identification and analysis of these genes and their mutations are providing ...

CoRDS collects contact, sociodemographic and health information about participants. This information is entered into CoRDS and linked to a unique coded identifier. Below are some examples of information requested on the Questionnaire that will be entered into CoRDS: Contact information: Name, Mailing Address, Phone Number, Email Address Sociodemographic information: Date ...

Cochlear implants are used in the cochlea (part of the inner ear) where they send electrical signals for activation of the auditory nerve to restore hearing to deaf patients. For patients without a functioning auditory nerve, there is an auditory brainstem implant (ABI), which is placed on the surface of ...

Hypothesis The use of topical dexamethasone in a single dose applied to the tympanic cavity during cochlear implant surgery modifies the capacitive component of the electrical impedance of the electrodes in the cochlea during the first days of the postoperative period. goals Primary objective To assess whether the use of ...

This study aims at investigating new automatic fitting techniques for cochlear implant patients based on objective measures. For this reason, the evolution of these neurophysiological measures, expressing the encoding of pure tones and speech, will be characterized in cochlear implanted patients as a function of post-implantation time and will be ...

Background Sensorineural hearing loss is the most common sensory deficit among older adults. There is no clinically proven method to predict the onset of this condition, as its occurrence is generally slow and progressive, affecting both ears equally. Recent studies have documented that hearing loss in older adults is independently ...
